MANIFOLDING-BOOK.

Specification of Letters Patent.

Patented Sept. 2, 19.13.

Application filed August 16, 1911. Serial No. 644,296.

To all whom it may concern:

Be it known that 1, JOHN Amman Pancrvan, a subject of the King of Great Britain, residing at lVinnipeg, in the Province of Manitoba and Dominion of Canada have invented new and useful Improvements in h Ianifolding-Books, of which the following is a specification.

The invention relates to sales or counter books and more particularly to the class of manifolding books.

The primary object of the invention is the provision of a book of this character in which a carbon transfer sheet will be conveniently held so that the same will gravitate between the original and duplicate leaves of a continuous strip upon the pulling outwardly of the said strip from the book.

Another object of the invention is the provision of a book which is simple in construction, light in weight, and inexpensive in IIlflIllIftlCtllI'C.

A further object of the invention is the provision of a sales-book which is susceptible of rapid and convenient manipulation, and that will firmly hold its leaves, and also will permit the insertion and removal of a carbon sheet in a ready and convenient manner.

Further objects will be in part obvious, and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combination of clcments, and arrangement of parts, which will be exemplified in the description hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

Tn the drawings: Figure 1 is a perspective view of the book open, with a leaf partially raised to permit of the positioning of the carbon-sheet between it and the adjacent leaf. Fig. 2 is a vertical longitudinal sectional view through the leaves and cover. Fig. 3 is a perspective view of the continuous leaves of the pad, the same being shown separated. Fig. 4 is a plan view of the book open, showing the carbon-sheet overlying a leaf, the outermost leaf being shown in section and uncovering the said carbonsheet. Fig. 5 is a sectional view on the line 55 of Fig. 4.

Similar reference characters indicate corresponding parts tl'iroughout the several views of the drawings.

Referring to the drawings by numerals, the manifolding book comprises a bottom cover 10, preferably constructed from pasteboard with a suitable decorated or marbleized outer surface, and is relatively thick to afford the requisite stiffness thereto, the bottom cover being connected by a flexible back 11 to a front or top cover 12 which is of a shape corresponding to the bottom cover, but is of less thickness than the same, although possessingsufficient stiffness, the outer face of the top or front cover being decorated or marbleized in a like manner as the bottom cover. I'lowever, the bottom and top covers 10 and 19., respectively may be covered with cloth or other suitable material, if desired.

Fixed to opposite end edges of the bottom cover 10 are clamping strips 13, the same being formed preferably from metal and provided with inturned gripping flanges 1 1 designed to overhang the inner face of the bottom cover 10. Engaged in the clam p ing strips 13 are the opposite end edges of a removable paste-board sect-ion 15 which is formed either from stiff paste-board or other material, on which is supported the writing pad, presently described.

Secured to the section 15 is the writing pad, comprising a strip 16 folded zigzag into individual leaf portions 17 and 18 which form alternate original and duplicate leaves perforated at the crease lines or folds in the strip, so that both the original and duplicate leaves may be separated, when desired. Each duplicate leaf 18 in the strip 16, near its upper edge, is provided with spaced apertures 19 which permit the said leaf to be inserted and clamped in a loose leaf binder, in the ordinary well-known manner, when it is desired to file the same away for future reference. The section 15 supporting the pad is slidably engaged between the flangcs 14 of the clamping strips 13 and the bottom cover 10 for the convenient removal of the pad and the inscrtion of a new one in its place when the pad becomes exhausted.

Fixed to the inner face of the bottom sec tion 10 at the inner edge thereof is one longitudinal edge of a flexible strip or web 20, the opposite longitudinal edge of which is formed to provide a casing 21, in which is loosely engaged the cross connecting portion 22 of a U-shaped wire frame 23, the ends thereof being bent to form double limbs arranged in parallelism with each other for supporting a carbon sheet 25, the latter, near opposite end edges, being folded; and in the folded portions are provided spaced parallel openings or perforations 26, through which are passed the limbs 24 for the detachable mounting of the carbon sheet upon the frame, the carbon sheet '25 being adapted for interposition between the outermost original and duplicate leaves 17 and 18, so that upon a single writing .upon the original leaf, a copy thereof will be produced upon the duplicate leaf, as will b clearly obvious.

An important advantage of the construction of the pad is that the originalleaf 17 is so folded that its free edge lies in the direction of the flexible back 11, so that upon separating the said leaf, it is an easy matter to turn the carbon sheet 25, so that the same will lie between the original and duplicate leaves, without wrinkling the carbon sheet or tearing or disturbing therelationship of the said original and duplicate sheets, when positioned for receiving a writing, and also avoiding the possibility of the carbon-sheet being inadvertently placed between the original and duplicate leaves with its coated face upward, as the same .will

be disposed downward in neutral position I for receiving the impression which is transmitted to the duplicate leaf through the original leaf and carbon sheet.

A further important feature of the con- .struotion of the pad and the particular mounting of the carbon sheet holding frame 23 is that the said carbon sheet will automatically fall into proper position between the outermost original leaf 17 and the duplicate leaf. It will be seen that when the.

user of the book pulls upon the original leaf 17 it draws the duplicate leaf therewith and also the next original leaf, so that when the first original and duplicate leaves have been removed,-the. second original leaf will fall upon the carbon sheet which has previously gravitated onto the second duplicate leaf. Y

What is claimed is: t

A manifolding book comprising a bottom and top cover, a flexible back connecting the same, a casing fixed to theinner face of the bottom cover at the inner edge thereof in alinement with the flexible back, a U-shaped wire-frame loosely engaged at its medial stretch in the said casing whereby its limbs will lie transversely of the bottom and top covers, the said limbs of the frame being doubled on themselves and providing:

rounded free ends thereof and a removable carbon sheet having folded and perforated ends adapted to receive the doubled limbs of the frame for the mounting of the carbon sheet thereon. 7

In testimony whereof I aflix my signature in presence of two witnesses.
